3 of 5 Decent upper September 20, 2022
:  
The upper looks great there was only one issue with fit and finish. There was too much build up of the coating on the upper reciever in the take down pin holes perventing the pins from pushing through. The fix was to run a drill bit into the holes and ream it out. After doing this everything worked perfect.

5 of 5 Out done them selfs June 7, 2021
: Corey Neuenschwander from Jenera, OH United States  
If you're in the market for a pre-assembled, attention-grabbing, accurate, short barreled upper? Then stop looking and purchase this five Star beauty. This is the third upper I've purchased from this company and have not one complaint. All completed uppers come pre-assembled and ready to pop your pins right through, drop in your charging handle, bolt carrier group, slide in a fresh mag and aim down the range. The 7.5 inch is so far my favorite for practice clearing rooms and crowded areas. I look forward to using this in close combat Target tournaments. Thank you Mass defense for not only a sharp, badass, addition to my tool, but for the speedy delivery, the extra swag and always having my back.

: Travis Miller from Salem, OR United States  
Been needing a 5.56 pistol upper for a while now and honestly had forgotten about MAS (even though i have multiple pieces from this company). I found exactly what i wanted and it arrived faster than expected. Looks great, functions perfectly.

5 of 5 Good Quality and Great price September 26, 2020
: David Estridge from Rock Hill, SC United States  
Great quality, fit and finish  and just what makes my new build look extremely nice.
This is my second purchase from you and i have never been disappointed what the product and fast delivery. I also purchased BCG and charging handle and they were already in the upper, so in 2 minutes after opening the box my build was complete. Will buy again.
